We have been given a scatter plot of a projectile motion and we have been asked to choose the correct statements out of the given statements. Let us analyze of the given options one by one and thus we can conclude which ones are correct and which ones are incorrect.
(A) The shape of the scatter plot does not look like the graph of an exponential function, therefore, this statement is not true.
(B) The shape of the given scatter plot does look like a quadratic graph, therefore, this statement is true.
(C) The shape of the given scatter plot does not look like a line, therefore, this statement is false.
(D) The height doesn't always change it the same rate. It initially increases at a rapid speed and then increases at a slow speed, at vertex it becomes constant and then starts to decrease. Therefore, this statement is false.
(E) Since height doesn't change at a constant rate, therefore, this statement is true as well.
The correct statements are (B) and (E).
Step-by-step explanation:
Tn = dn + T0
(dn is difference between the numbers and T0 is the term before the first one given to you)
Tn= 3n + 3
Answer:
Step-by-step explanation:
Given that prices for a pair of shoes lie in the interval
[80,180] dollars.
Delivery fee 20% of price.
i.e. delivery fee will be in the interval [4, 9]
(1/20th of price)
Total cost= price of shoedelivery cost
Hence f(c) = c+c/20 = 21c/20
The domain of this function would be c lying between 80 to 180
So domain =[80,180]
---------------------------------
Amount to be repaid = 42 dollars
Once he received this amount, the price would be
105+42 =147
But since price range is only [21*80/20, 21*180/20]
=[84, 189]
Since now Albert has 147 dollars, he can afford is
[80,147]
Answer: Remember, the formula to calculate combinations is nCr = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

Answer:
2(3x+16)
Step-by-step explanation:
Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4
4(x + x + 7) − 2x + 8 − 4
When x=1 , the expression becomes 4(1+1+7)-2(1)+8-4=38
When x=2 , the expression becomes 4(2+2+7)-2(1)+8-4=44
Plug in x=1 and check with each expression
6x + 11 =6(1) +11= 16
3(x + 7) = 3(1+7)= 3(8)= 24
2(3x + 16) = 2(3(1)+16)= 38 , we got same answer when x=1, now check with x=2
2(3x + 16) = 2(3(2)+16)= 44
3x + 16= 3+16= 19
